Application February 6,

6 Claims.

The invention relates to improvements in receptacles and has reference to the type of envelopes, wrappers, bags, sacks, or like enclosures, made of paper or of transparent cellulose material, provided with closure members which are adapted to be folded into position to close the open ends of said envelope, wrapper, bag, sack, or like enclosures without sealing said members with a sealing substance.

In a copend'mg application Serial No. 655,385 filed Feb. 6, 1933, we have described and claimed an envelope in which certain sections of the blank thereof dened by transverse score lines are folded one upon the other to provide pockets at one r end of the envelope either of which is adapted t receive a closure member formed from another transverse section of the blank. The first-named transverse sections are the same length, which is less than the total width of the blank, said width including a central section from which the face or front of the envelope is formed and two side sections or flaps that are adapted to be overlapped to constitute the back of the envelope. However, the length of said transverse sections is greater than the width of said central sections and, as a consequence, in order that the ends of said firstnamed transverse sections may be secured together by a simple overlapping operation after said sections have been folded one upon the other and the side sections have been overlapped, the adjacent ends of said transverse sections are relatively offset or staggered so that one projects beyond the other.

In accordance with the present invention it is proposed to provide a blank for an envelope in which the amount of material used therefor is reduced to a minimum and this is accomplished by the provision of two transverse sections for the blank which are employed to form a pocket for the reception of the closure member of the envelope and are made of different lengths. More specically, the shorter of the two transverse sections which combine to form a pocket for receiv- F ing the closure member is of a length equal to the width of the central section of the blank which forms the front of the envelope and to the length of the closure member which is to be inserted into said pocket.

The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for the purposes of illustration, is shown in the accompanying drawing wherein:-

Figure 1 is a plan view, partly broken away, of the back of the envelope showing the same in its open position.

Figure 2 is an enlarged vertical section on the line 2 2 of Figure 1.

Figure 3 is a fragmentary plan view of the front of the envelope in its closed position.

1933, Serial No. 655,386 (Cl. 229-76) Figure 4 is an enlarged section on the line 4-4 of Figure 3.

Figure 5 is a plan view of the blank from which the envelope is formed, and

Figure 6 is a similar View showing the envelope at an intermediate stage of the folding operation. Envelopes or other containers made in accordance with the present invention are especially adapted for use in the transmission of other than first class mail, commercial papers and the like, or may be made up in the form of bags of various zes for containing different kinds of commodities. The envelope, wrapper, bag, sack, or like enclosure may be made of any suitable material such as paper of the proper weight, or of any y other desired material such as of transparent cellulose nature, and the blank cf the class described when constructed from a blank of the present invention do not require clasps, clips or other fastening means for securing the closure member of the said envelope, wrapper, bag, sack, or of other like enclosure in its operative position.

As shown in the drawing, the blank which may be made of any desired material, is scored along the longitudinal lines '7 to form a central section 8 extending the length of the blank and also the side sections or flaps 9 which constitute the back of the body portion of the envelopes when said ilaps are folded along said score lines into overlapping relation. The central section is scored 10 to define, with the of the completed entransversely along the line lines 7, the front or face velope.

Other score lines 11 and 12 define three transverse sections 13, 14 and 15, the first-named of which is preferably of a length equal in width to the central section 8, while the transverse sections 14 and 15 are both of the same length as the combined width of the sections 8 and 9.

The first operation of forming the envelope l from the blank is to fold the latter on the line 10 in such a manner that the transverse section 13 will overlie the adjacent end of the central section 8 and this operation is followed by folding on the line 11 in an opposite direction so that the section 1-'l will be superimposed upon the section 13, thereby forming a single recess or pocket l5 (Figure 2) into which is adapted to be inserted a closure member now to be described.

This closure member is formed from the transverse section 15 and is provided with the diagonal score lines 17 which combine with the adjacent extremities of the longitudinal lines 7 to form the corner folds 18 that are tucked in, as best shown in Figs. 1 and 6, when the opposite ends of the sections 14 and 15 are folded over into overlapping relation along the extensions of the score lines 7. When said ends are thus folded the blank assumes the position shown in Figure 6 llO in which the diagonal score lines cause the closure member to be tapered so that it can be more easily inserted into the pocket 16. Along the free longitudinal edge of the section 15 constituting the closure member the same is provided with an intermediate and two end tabs 19 which are superimposed one upon the other when the blank is folded in the position shown in Figure 6 and which are folded against the closure flap when the latter is inserted into the pocket 16, said tabs then extending upwardly, as indicated in Figure 4, so that the upper ends thereof can be readily grasped and pulled outwardly when it is desired to open the envelope. In order that the overlapped ends of the sections 14 and 15 and the end tabs 19 may be secured together when said end portions are folded in the position shown in Figure 6, a strip of adhesive 20 is applied along one longitudinal edge of the blank, so that said edge will adhere to the opposite overlapped edge when this portion of the folding operation is accomplished.

To complete the formation of the envelope, the side sections 9 are folded upon the lines 'I to overlapped relation with each other and with the end portions of the sections le and 15 better exposed when the parts are in the position of Figure 6. The left hand section 9 is first folded over and attached to the latter` sections by a strip of adhesive 21 applied to one end of said side section and thereafter the right hand section 9 is folded over and attached to said transverse sections and to the left hand section 9 by the strip of adhesive 22 which extends along one longitudinal edge of said right hand section and also one end thereof. This gummed end portion and the portion 21 thus adhere to the ends of the transverse section 14 so that no pocket will be formed on one side of the envelope to receive the closure member. The gumming operation described causes said side sections to assume the position shown in Figure 1 and when the gummed end flap 23 is folded over upon said sections, as shown in the latter figure, to close one end of the envelope, the latter is completed. The closure member which has thus been formed by the transverse section l5 may be folded on the score line 12 and inserted into the pocket 16 as shown in Figure 4 with the tabs 19 extending upwardly therein as previously described, whereupon the adjacent end of the envelope will be closed.

An envelope, bag, Wrapper, sack, or similar enclosing device or closing integument or covering formed from a blank scored to provide a central section and side sections which combine to form the front and back of an envelope when said side sections are overlapped, transverse sections of different lengths contiguous to one end or said central section and fcldable one upon another to provide a pocket, and another transverse section at one end or" the blank forming a closure member insertable into said pocket, said transverse sections constituting an extension from one end of said central section.
